Dry hair often causes frizz and split ends and lacks shine. Inspired by the ever-hydrated, never dry aloe plant, Biolage Hydra source Shampoo helps optimize moisture balance and protect against future damage for healthy looking hair. This salon professional hair treatment gives you up to 15X more moisturized hair after just one application.*

*When using the professional products system of Hydra source shampoo, conditioner and leave-in tonic vs. a non-conditioning shampoo.
